function hook_commerce_product_can_delete in Commerce Core 7

Lets modules prevent the deletion of a particular product.

Before a product can be deleted, other modules are given the chance to say whether or not the action should be allowed. Modules implementing this hook can check for reference data or any other reason to prevent a product from being deleted and return FALSE to prevent the action.

This is an API level hook, so implementations should not display any messages to the user (although logging to the watchdog is fine).

Parameters

$product: The product to be deleted.

Return value

TRUE or FALSE indicating whether or not the given product can be deleted.
